Stick Welding
Stick Welding: The Ultimate Welding Technique
If you are a beginner or a more experienced welder, you can count on stick welding!
Stick welding, also known as Shielded Metal Arc Welding (SMAW), is a reliable welding technique due to its efficient production of solid and robust metal bondings and advances in electrode technologies. Because of its many advantages, there is yet to be a welding technique to beat stick welding when it comes to metal adaptability and mobility. Moreover, it is also ideal due to its seamless operations, regardless of difficult circumstances.

Introduction to Stick Welding
Stick welding is just one of many forms of arc welding that have been used for decades in various industries. Another name for it is Manual Metal Arc Welding, or MMA Welding. Some people refer to this method as being commonly known as Arc Welding.
For the beginners out there, stick welding is an electric arc welding using flux-coated rod-shaped metal electrodes. Stick commonly uses the following electrodes: 6010, 6011, 6013, 7018, and 7024. The most frequent widths for these electrodes are 1/8- to 5/32-in. Except for 7024, all these electrodes can be used for all positions during welding.
How it Works
In stick welding, an arc is formed between the ends of a metal electrode because of an electric current that flows through the electrode. The arc melts the metal, the rod, and the parts that need to be linked. Ejected from the electrode, the metal combines or merges with the workpiece in a molten weld pool.
The metal and the workpiece are called the base metal, and the metal added to the joint is called filler metal. Filler metal is always added to the junction during stick welding.
The power supplied to the electric arc can be alternating current (AC) or direct current (DC). DC arc welders offer a smoother arc that works better on thin materials but is more expensive than AC arc welders.
Stick welding is a consumable electrode procedure because the electrode frequently melts away and joins the welded structure. A protective gas that shields the weld and aids arc stabilization is released when a portion of the electrode covering heats up due to the arc.
As the residual layer melts, it creates a protective slag layer over the molten weld pool. This slag layer must be removed when the weld has cooled and shielded, and the weld is formed while it solidifies. The flux gases can protect the molten weld without additional shielding devices like high-pressure gas cylinders, regulators, or hoses.
What Can Shielded Metal Arc Welding (SMAW) be Used on
Stick welding can be used to build vessels, pipes, tanks, bridges, automobiles, farm equipment, metal art sculptures, trailers, and more. It is a versatile technique used on various metal types.
It works very well for welding mild steel, stainless steel, and cast iron. Maintenance projects, building projects, and manufacturing projects often use these welds.
Stick welding can be used less commonly to join non-ferrous metals like copper, nickel, and even aluminum. However, it is much more complicated and frequently needs specific electrodes. We recommend looking at a MIG or TIG machine for these tasks.
Pros vs Cons Overview

- Not Ideal or Thin Materials
Pros of Stick Welding
Stick welding is versatile and easily adjustable, as it involves swapping out the electrode while keeping the rest of the welding apparatus in place. Having multiple welding rods on hand simplifies and expedites changing the electrode.
Since stick welders generate their own gas, they don’t need shielding gas. You won’t need to supply shielding gas cylinders because carbon dioxide is the most commonly produced shielding gas. Comparatively speaking, stick welding requires less equipment than MIG and TIG welding.
Stick welding is perfect for those who don’t want the hassle of a gas tank.
Depending on the kind of metal you want to weld, a box of different welding rods is included with the primary components needed for a stick welding machine, including a stinger lead and ground lead.
It is quiet and perfect for indoor areas where noise may disturb nearby businesses or other people. Stick, shielded metal arc welding (SMAW) may be done practically anywhere and is very portable and manageable.
One of the most popular techniques for welding while moving is the electrode flux method, as it produces gas on its own. You can count stick welding as a great outdoor project regardless of rain or windy weather.
Since little equipment is needed, stick welding equipment setup is reasonably priced. Without requiring a lot of parts or setup, such as shielding gas cylinders and hoses, or prior experience with laser, MIG, or TIG welding, it’s simple to set up different activities.
Cons of Stick Welding
SMAW produces a lot of smoke, which can be uncomfortable, especially in small or cramped spaces. Although it is usually slower than MIG or TIG welding, which is moderately to quickly efficient, it is still a vital welding process. Stick welders are, therefore, only recommended in some industries where great productivity is necessary.
While many welding rods used in this process are moisture-resistant, damp environments can harm the low-hydrogen welding rods frequently employed in arc welding. Since welding is a manual operation, automation would be necessary to increase the technique’s efficiency.
Error rates are higher when welding in specific positions, and working with thicker metals can be difficult and necessitate more planning and workstation reorganization.
Slag and debris are frequently left behind during stick welding because the gas used from the electrode creates them to shield the arc. Slag must be eliminated by sanding the surface smooth after chipping with a wire brush, hammer, or chisel.
Working with thinner metals is difficult; MIG or TIG welding techniques work well with them.
